论文摘要
我们建议通过带电的标量单元组与标准模型Lepton扇区耦合的GEV尺度Majoraana暗物质（DM）的最小模型。我们表明，独立于自旋的DM核散射横截面（$σ_ {\ Mathrm {si}} $）与各种理论和实验性约束允许的参数值的DM Relic密度之间存在抗相关性。此外，我们发现，即使DM耦合是订单统一的，$σ_{\ Mathrm {si}}} $低于当前的实验界限，但在中微子地板之上。此外，我们表明可以使用例如单基金的生产和相同签名的Higgs对生产。
We suggest a minimal model for GeV-scale Majorana Dark Matter (DM) coupled to the standard model lepton sector via a charged scalar singlet. We show that there is an anti-correlation between the spin-independent DM-Nucleus scattering cross-section ($σ_{\mathrm{SI}}$) and the DM relic density for parameters values allowed by various theoretical and experimental constraints. Moreover, we find that even when DM couplings are of order unity, $σ_{\mathrm{SI}}$ is below the current experimental bound but above the neutrino floor. Furthermore, we show that the considered model can be probed at high-energy lepton colliders using e.g. the mono-Higgs production and same-sign charged Higgs pair production.
